Abstract: A rim lock includes interior and exterior lock assemblies. Each lock assembly includes a lock cylinder that is removable without removing the rim lock from the door.

Abstract: To cause a door from being forced open or broken to gain access, a safety door comprises a central actuator and a plurality of bars radially extending at spaced apart locations from said central actuator sufficient in number and spacing to reinforce substantially the entire door. The central actuator is pivotally mounted within the door and each of the plurality of bars has one of its ends pivotally mounted to the actuator to cause the bars to be retracted or extended by rotation of the actuator. There are at least four bars with at least one bar extending in each of the four sides of the door framework.

Abstract: A free-wheeling lever handle controller for operating a mortise lock provides free-wheeling functionality while maintaining the full operational characteristics of various mortise lock functions. A lock mode receiving mechanism connectable to the lock output is used to detect the unlocked and locked conditions of the mortise lock, and correspondingly engage and disengage the free-wheeling mechanism. The free-wheeling mechanism has a split shaft connected between a handle on the controller and a handle input on the mortise lock. The two halves of the shaft may be coupled and uncoupled via a shaft lock movable perpendicular between locked and unlocked positions. In the unlocked position the shaft lock connects the two halves of the shaft to rotate together when the handle is turned. In the locked position the shaft lock disengages the two halves of the shaft to rotate separately and allow the handle to free-wheel with operating the door latch.

Abstract: A rotatable control device including a body housing a control structure and having an external box; a control shaft journalled in the boss for rotation about an axis and having an internal portion connected to the control structure and an external portion extending outwardly from the boss; an operating handle having an inner end portion connected to the external portion of the control shaft, a gripping end portion for rotating the control structure between first and second positions and an intermediate portion; first and second locking structure circumferentially spaced on the body at locations corresponding to the positions of the intermediate portion of the handle when the control structure is in the first and second positions, respectively; a slider member slidably mounted on the intermediate portion of the handle for reciprocative movement between locked and unlocked positions; interlocking structure for cooperating with the first and second locking structure, when the handle is in the first and second po
